Submission + - Taking STM images 100 times faster

Roland Piquepaille writes: "Very few of you have used a scanning tunneling microscope (STM), an essential tool to study nanoscience. And you might think that it's as easy to take a picture of an atom with an STM as it is to take a shot with your digital camera. In fact, the imaging of individual atoms with a STM is awfully slow. But now, U.S. researchers had a very simple idea to accelerate this process. By adding a simple radio transmitter, they are able to make atomic-level microscopy at least 100 times faster. A typical STM has currently a sampling rate of about one kilohertz. This new radio-frequency scanning tunnelling microscopy can operate a thousand times faster. Very bright idea! But read more for additional details and a picture of a scanning tunneling microscope. I'm sure it's different from your expectations."
